Description
Diversified Technologies, Inc. (DTI) designed and developed a high stability modulator system for a commercial linear accelerator application. The DTI modulator delivers significant advantages in klystron performance through highly reliable functionality as well as flicker- and droop-free operation from 50-500 μs up to 400 Hz (duty limited). The main assemblies on the DTI system consist of a controls rack, high voltage power supply
(HVPS), modulator, and cooling manifolds for the modulator, high voltage power supply and klystron tube.
Two HVPS (upgradeable to four) provide stable and accurate DC voltage which is used to drive a CPI VKP - 8352C UHF-band pulsed klystron for the linear
accelerator. A solid state series switch, based on DTI’s patented design, provides both pulse control and arc protection to the klystron. Operating with four HVPS, the DTI modulator is able to operate at a maximum average power of ~750 kW at 105 kV, 47 A nominal.
